Product Introduction
The roadheaders are advanced, self-propelled, extremely powerful rock-cutting machines designed to excavate roadways, tunnels and chambers continuously without using explosives. Powered electro-hydraulically, they are used extensively in coal mining, mineral mining and underground construction projects, where their ability to excavate the desired profile without causing harmful vibrations is highly valued for both environmental and safety reasons.
Main CharacteristicsCompact structure , body is low , with a low center of of gravity , easy to operate , and operate steadily. 2. Cutting head size can be 700x550 or 750x550mm , it has good cutting speed when cut medium hard coal rock. Cutting pick are reasonable arrangement , strong ability of cutting , posses spray both inside and outside , good dust-proof effect .The roller shearer is used for mechanized coal mining in longwall coal face, and can also be used for mining other minerals such as potash or shale.At present, the cutting height of the drum shearer is 0.65~5.0m, which can cut down various cutting impedance coal seams .
